    Reuse the docs deps to benefit from constraints
    
    Tox trying to install latest versions for building releasenotes,
    which may not be supported by stable and lower branches,
    so should be restricted by respective version's upper-constraints.txt
    This ps to reuse upper-constraints.txt from docs deps
